2004 Ford Thunderbird

The 2004 Ford Thunderbird is a retro-styled roadster that pays homage to the original Thunderbird of the 1950s. It was offered with a single engine option: a 3.9L V8 producing 280 horsepower and 286 lb-ft of torque. This engine was paired with a 5-speed automatic transmission. People generally like the Thunderbird for its unique styling and comfortable ride, but some dislike its limited practicality and relatively poor fuel economy. Common complaints include electrical issues, particularly with the instrument cluster, and issues with the convertible top mechanism.

Summary

The 2004 Ford Thunderbird has a mix of mechanical and electrical issues to be aware of. While some are relatively minor and inexpensive to fix (e.g., ignition coils, blower motor resistor), others, such as convertible top issues and instrument cluster failures, can be more costly. Overall, the vehicle may require some maintenance to keep it running smoothly, with potential for moderate to high repair costs depending on the specific problems encountered.
